Problems solved by technology

[0004] The CBTC system stipulated in the current standard is composed of subsystems such as ATS (Automatic Train Supervision, automatic train supervision system), computer interlocking, automatic train protection, automatic train operation, and data communication. There are complex interface connections between the subsystems, and the same function There are too many devices involved, the system structure is complicated, and the software design difficulties or software errors caused by the complexity of the system are becoming more and more prominent;
[0005] Since the development of each subsystem is not synchronized, in order to be compatible with the processing methods of the existing system and realize the degraded operation when some equipment fails, the CBTC system retains some non-essential equipment in the mobile block tracking solution, resulting in the cost of the whole life cycle of the system High, especially for intercity railways with long lines and large distance between stations, the current construction and operation costs are unacceptable;

Embodiment 1

[0033] The embodiments of the present invention aim at the deficiencies of the existing technology, make full use of the rapidly developing computer and communication technology, and propose a system that can effectively reduce the system cost based on the existing CBTC system structure through a more concise architecture design and function allocation method. It is a low-cost and high-efficiency new CBTC system that improves the anti-interference ability of equipment and shortens the train tracking interval. Hereinafter, the new CBTC system in the embodiment of the present invention is called N-CBTC system.

[0034] The system structure and interface schematic diagram of the N-CBTC system provided by the embodiment of the present invention is as follows figure 1 As shown, it is composed of ATS, VOBC (Vechile On-Board Controller, on-board controller), WCU (Wayside Control Unit, wayside controller) and DCS (Data Communication System, data communication) subsystems. The solid li...

Embodiment 2

[0041] The schematic diagram of the typical operation scene of the train in the CBTC system of the present invention is as follows: image 3 As shown in , the schematic diagram of the position of VOBC1 when reentry is indicated by the dotted box.

[0042] Turnout 1-3 is a group of double-action turnouts controlled by WCU; VOBC1, VOBC2, and VOBC3 are trains in normal operation on the 3 lines. The operation plan is that VOBC2 runs on the downlink, VOBC1 tracks the operation of VOBC2, turns to the uplink at the 1-3 turnout, and then runs on the uplink, and VOBC3 tracks VOBC1 after the VOBC1 turns back.

[0043] This embodiment shows VOBC1 tracking VOBC2 in chronological order, and the running scenarios of VOBC1 and VOBC3 when dealing with possible turnout resource conflicts. Only important change events are described at each moment, and undescribed events are explained in the same way as before. periodic processing.

[0044] At time T0, VOBC2 completes the initialization and po...

Abstract

The embodiment of the invention provides a train operation control system. The system comprises that a train operation plan is generated, issued and adjusted by a train automatic control system; high-precision train autonomous positioning is realized by a vehicle-mounted controller through correction of a train autonomous positioning system and a trackside transponder; a trackside controller receives commands which are transmitted by the vehicle-mounted controller and used for operating trackside equipment and controls the corresponding trackside equipment to actuate and lock to the corresponding position according to the command requirements; and a data communication subsystem performs data communication with each set of ground equipment via a redundant backbone network and realizes wireless transmitting and receiving of trackside controller information and vehicle-mounted controller information via a wireless communication antenna. CI and ground ATP equipment are reduced and WCU equipment is increased, and mutual resource coordination is performed via a mode of direct communication between adjacent trains and between the trains and the WCU so that system cost is reduced and train tracking efficiency is enhanced.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train operation control system. Background technique [0002] With the development of my country's national economy and the acceleration of urbanization, urban traffic congestion and traffic connection problems between large, medium and small cities and small towns are becoming more and more serious. As an important means of relieving traffic pressure, the pace of development of rail transit is accelerating. , the demand for urban rail transit and intercity railway construction is becoming stronger and stronger. [0003] As the "brain and nerve center" of rail transit, the pressure on the development of train operation control technology is increasing. At present, most of the urban rail transit lines under construction in my country choose to use the most advanced CBTC (Communication Based Train Control System, based on wireless communication train automatic control system...
